Montana and federal officials Tuesday released the final plan for cleaning up solvent-contaminated soils and groundwater in the Lockwood Superfund site.Read the full story.
The cleanup will take about 10 years and cost an estimated $14.3 million.
The report, called a Record of Decision, identifies the remedy for the site as approved by the state Department of Environmental Quality and the U.S. Environmental Protection Agency.

The chemicals, which are commonly used as degreasers and in dry cleaning, include tetrachloroethene (PCE), and its breakdown chemicals, trichloroethene (TCE), dichloroethene (DCE) and vinyl chloride.

In fact, 22 BNSF sites are listed on the state's priority cleanup list, with two — Livingston and Havre — ranked as a maximum priority and another 11 — including the rail yard and a tailings pile near Ryan Fields ballpark in Helena — considered high priorities. BNSF is the only company with more than two sites out of 208 businesses on the list.Read more.
BNSF representatives are up front about the on-site problems, and the company has spent millions of dollars installing monitoring and recovery wells, wastewater treatment plants and ditches in an effort to pump out contaminants and keep them from moving off-site.
But those who have tried to force the railroad to deal with migrating contaminants say the company is reluctant to acknowledge, test for or define any problems.
"I know they may have liability concerns, or they may be in litigation and don't want to do some things," said Denise Martin, section supervisor for the state hazardous waste site cleanup bureau. "I don't know their motivation, but there are other companies that are much more responsive."

"We have become aware that in some instances it doesn't take very much contamination in the groundwater, if the conditions are right, for there to be the potential for indoor air to become contaminated too," Martin said. "The toxicity is greater in the air than if you took a glass with it in and drank it, because you're getting the contaminants into the lungs where there's more thorough absorption.
"We want to make sure people are not drinking these chlorinated solvents, but there's an even greater risk if they're showering and inhaling the steam and contaminants that may be released."

a California, the District of Columbia, Massachusetts, and Nebraska did not respond to surveys. For these states, the data in table IV.1 are based on EPA’s survey responses alone and, for that reason, may be less reliable than for states having responses from both EPA and states. New York provided responses to only a few questions in our survey.
b “Other” indicates that the respondent was uncertain about the state’s financial capability.
* State officials in Idaho, New York, Missouri, Utah, Virginia, and Wyoming declined to participate in [the] telephone survey.

The purpose of this document is to provide a synopsis of trichloroethylene (TCE) inhalation toxicity values and provide the corresponding risk-based indoor air concentrations for use in vapor intrusion assessment. Table 1 summarizes the toxicity values and risk-based concentrations. Figure 1 provides a graphic comparison of the ranges of concentrations corresponding to each of the toxicity values.

The insurance policy for a medical research company's laboratory in Hamilton does not cover pollution caused by years of dumping hazardous waste into [the Bitterroot Valley Sanitary Landfill] nearby, the Montana Supreme Court said Tuesday.TCE, PCE, and vinyl chloride are among the contaminants of concern at the site. You can read the full story here.
The unanimous decision rejected claims by Corixa Corp., formerly Ribi Immunochem Research Inc., that it deserved coverage because the resulting contamination of groundwater was unexpected and unintentional. The court said the waste dumping was intentional, and therefore, Corixa's insurance policy did not apply.
For more detail on the contamination, the Montana Department of Environmental Quality (DEQ) has a full summary of findings and remediation strategy at the landfill in their Record of Decision (ROD).
